An Idiographic Approach to Uncovering the Structure of Narcissism

Narcissism has long been understood as dynamic yet measured statically. We test whether theoretically posited dynamic interplays among grandiose and vulnerable narcissism dimensions emerge in daily life using experience sampling method (ESM) data (N=172; Nobs=9,226). We capture idiographic narcissism dynamics using GIMME models, finding evidence for heterogeneous dynamics across people.
